What 2-D, 3-D, 4-D, 5-D, 6-D, 7-D, 8-D, 9-D, 10-D, and higher dimensional Polytope Numbers are included in this table. Link to Table of many 2-D and 3-D Figurate Numbers, including Constructable Numbers: Figurate Numbers, Sorted Eric Weisstein's World of Mathematics : Has Definitions and References For many terms below (Tetrahedral Number, Pentatope Numbers, Hypercube, etc.), except Jonathan Numbers, which are classes of sets of "Iterated Figurate Numbers" as defined in several of Jonathan Vos Post's publications as cited elsewhere on this page. See also References specific to Polytope Numbers. Who is the Mathematician/Webmaster who created this table?

1:

many sequences of Figurate Numbers start with 1. Hence, among other things, 1 is the first of the Triangular, Square, Pentagonal, Hexagonal, Heptagonal, Octagonal, Nonagonal, Decagonal and other Polygonal Numbers. It is also, after 0, the first Square, Cube, 4-D Hypercube, 5-D Hypercube, and so forth. It is also the first of many Polyhedral Numbers such as the Tetrahedron Tet(0). It is also the first of an infinite number of multidimensional Polytope Numbers such as the Pentatope (4-Simplex or Hypertetrahedron), Hyperoctahedron, 24-cell, Hyperdodecahedron, and Hypericosahedron -- these Polytope numbers are the subject of recent papers by this author, see References.

Four Nines Puzzle

"The Weekly Dispatch" of 4 February 1900, which ran a puzzle column by Dudeney, introduced a problem which is still provoking interest today. That problem was the Four Nines Puzzle, based on the even older Four Fours Puzzle, which is also discussed on this web page. Jonathan's page hotlinked here includes a complete list of equations representing, with four nines, every integer up to 314, and many beyond that. There is some deep theory towards the bottom of the page.

Four π Puzzle

Similar to the Four Nines Puzzle, and Four Fours Puzzle, mentioned above, What numbers can be made with four copies of the number "pi", or π? Jonathan's page hotlinked here includes a complete list of equations representing, with four "pi", every integer up to 1,000, and many beyond that. It is a useful teaching tool for geometry or algenra students to ask: "How can we construct the smaller whole numbers, under 100 for instance, using only all four copies of the number π, parentheses, and the arithmetic operators

"+","-","x","/"?

We also allow the use of exponentiation, radicals (especially the square root "sqrt"), factorial "!", and the floor function "|_ N _|" and ceiling function "|- N -|".

Definition of Factorial

Let us note that there are some unsolved mathematical questions about the Factorial Function N! The well-known definition is: 1! = 1 2! = 1 x 2 = 2 3! = 1 x 2 x 3 = 6 4! = 1 x 2 x 3 x 4 = 24 5! = 1 x 2 x 3 x 4 x 5 = 120 6! = 1 x 2 x 3 x 4 x 5 x 6 = 720 7! = 1 x 2 x 3 x 4 x 5 x 6 x 7 = 5040 8! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 = 40,320 9! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 = 362,880 10! =1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 = 3,628,800 ... and so on

Any Integer is the First Digits of Some Factorial

Believe it or not, your telephone number, your Social Security Number, or any other whole number important to you can be found as the beginning digits of some enormous factorial. John E. Maxfield proved this theorem: "If A is any positive integer having M digits, there exists a positive integer N such that the first M digits of N! constitute the integer A." ["A Note on N!", John E. Maxfield. Kansas State University, Mathematics Magazine, March-April 1970, pp.64-67; supported in part by a National Science Foundation grant].

Factorials of Negative, Fractional, and Complex Numbers

For non-integers, and for complex numbers, the universally accepted generalization of the Factorial Function is the Gamma Function. Discussion of that shall be reserved until I provide my analysis of the Four Nines Puzzle as applied to Complex Numbers, such as first appear with sqrt (-9) = 3i.

Square-less-one Factorials

In our solutions to the Four Nines Puzzle, we often add to or subtract something from a factorial, and then take a square root. Typically, this is not a whole number, so we round down, or round up (floor or ceiling). This leads to the question: When is N! + 1 a perfect square? Or, equivalently, When is sqrt (N! + 1) a whole number? The only solutions known are: 25 = 4! + 1 = 5 x 5 121 = 5! + 1 = 11 x 11 5041 = 7! + 1 = 71 x 71 Nobody knows if there are any other perfect squares one more than factorials. Clearly related is a paper by Berend and Osgood: [Journal of Number Theory, vol. 42, 1992] which proves that for any polynomial P of degree > 1 the set of positive integers N for which P(X) = N! has an integral solution X, is of zero density. This paper explicitly says that it is not known if the equation X^2 - 1 = N! has only finitely many solutions. We also don't know if there are an infinite number of primes of the form n! + 1. We also don't know if there are an infinite number of primes of the form n! - 1. The largest such prime that we know is 3610! - 1. It has 11,277 digits [Caldwell, title to be added here, 1993] By the way, there is a fairly elementary proof that, except for 0!=1 and 1!=1, NO factorials are perfect squares. That fairly elementary proof, though, uses a heavy mathematical result known as Bertrand's Postulate, also known as Chebychev's Theorem (after the man who first proved it). This Theorem says that there always exists at least one prime between N and 2N, if N>2. Erdos gave a genuinely elementary (although neither short nor obvious) proof. This will all be inserted here or linked to in a later version of this web page. Special Thanks to Dr. George Hockney, NASA/JPL, for informal discussion and review in January-February 2004.
