In mathematics, a pandigital number is an integer that in a given base has among its significant digits each digit used in the base at least once. For example, 1234567890 (one billion two hundred thirty-four million five hundred sixty-seven thousand eight hundred ninety) is a pandigital number in base 10.
Given this formula, Rayo's number is defined as: [5] The smallest number bigger than every finite number with the following property: there is a formula () in the language of first-order set-theory (as presented in the definition of ) with less than a googol symbols and as its only free variable such that: (a) there is a variable assignment ...
The smallest example of a number whose optimal expression is not of this form is 353942783. It is a prime number , and therefore also disproves a conjecture of Richard K. Guy that the complexity of every prime number p is one plus the complexity of p − 1 . [ 5 ]
For example, for the array of values [−2, 1, −3, 4, −1, 2, 1, −5, 4], the contiguous subarray with the largest sum is [4, −1, 2, 1], with sum 6. Some properties of this problem are: If the array contains all non-negative numbers, then the problem is trivial; a maximum subarray is the entire array.

The result of calculating the third tower is the value of n, the number of towers for g 1. The magnitude of this first term, g 1, is so large that it is practically incomprehensible, even though the above display is relatively easy to comprehend. Even n, the mere number of towers in this formula for g 1, is far greater than the number of Planck ...
99,991,011 = largest triangular number with 8 digits and the 14,141st triangular number; 99,999,989 = greatest prime number with 8 digits [43] 99,999,999 = repdigit, Friedman number, believed to be smallest number to be both repdigit and Friedman
In base 10, there is thought to be no number with a multiplicative persistence greater than 11; this is known to be true for numbers up to 2.67×10 30000. [1] [2] The smallest numbers with persistence 0, 1, 2, ... are: 0, 10, 25, 39, 77, 679, 6788, 68889, 2677889, 26888999, 3778888999, 277777788888899. (sequence A003001 in the OEIS)
