8132015 is a composite, deficient, evil, happy, odd, polite, unprimeable, and wasteful number.
81315 can be written as the difference of two squares in 12 different ways: 81315 = 3062 - 1112 = 3622 - 2232 = 4062 - 2892 = 6582 - 5932 = 9262 - 8812 = 10622 - 10232 = 27182 - 27032 = 31342 - 31212 = 45222 - 45132 = 81342 - 81292 = 135542 - 135512 = 406582 - 406572.
81315 is a 8133-gonal and 27106-gonal number.
Examples
of Sequence Numbers:
|
A sequence number is an
integer that produces recognizable sequence.
To produce this sequence you take the inverse of the sequence number,
and calculate the digital expansion. Example:
9801 is a sequence
number. The inverse of 9801 is
1/9801. When you change this fraction
into a decimal number you get 0.0001020304050607… This sequence counts, using 2 digit
strings, from 00 to 97, without error.
If you would like to
check some of these out I invite you to do so. The mathematics is simple. You don’t have to do anything harder than
adding, subtracting, multiplying and dividing. But for many of them you will want to do it
on your computer – I would recommend using the Wolfram Alpha website: www.wolframalpha.com .
I also urge you to use
the Online Encyclopedia of Integer Sequences website to verify that the digit
sequence you get matches what the sequence is supposed to be giving: www.oeis.org .
The following is a list
of some of the known sequence number, and the digital sequences they produce.

NUMBERS THAT PRODUCE COUNTING SEQUENCES:
81 produces a digital sequence that counts
from 0 to 7, written in one digit strings.
9,801 produces a digital sequence that
counts from 00 to 97, written in two digit strings.
998,001 produces a digital sequence that

9,999,800,001 produces a digital sequence
that counts from 00000 to 99997, written in five digit strings.
This patterns continues.
999,999,999,999,998,000,000,000,000,001
produces a digital sequence that counts from 000000000000 to 999999999997
without error, written in 12 digit strings.
It does it through one division operation: 1/999999999999998000000000000001. Counting from zero to nine-hundred
ninety-nine trillion, nine-hundred ninety-nine billion, nine-hundred
ninety-nine million, nine-hundred and ninety-nine thousand, nine-hundred
ninety-seven without error! I don’t care
if there is a mathematical explanation for how this is possible, it is still
pretty AMAZING.
But, hold on. There are more!
