31,018,606,641

[Math.]  Sum of the first 593 cube numbers:

13+…+5933 = 31,018,606,641 = (1+…+593)2 = 176,1212.

31,228,191,225

[Math.]  Sum of the first 594 cube numbers:

13+…+5943 = 31,228,191,225 = (1+…+594)2 = 176,7152.

31,381,886,305

[Math.]  31,381,886,305 = 12+33+55+77+911.

31,438,836,100

[Math.]  Sum of the first 595 cube numbers:

13+…+5953 = 31,438,836,100 = (1+…+595)2 = 177,3102.

31,509,019,100 & 31,509,019,101

[Math.]  The 14th square number that is the sum of squares of 2 consecutive numbers: 31,509,019,1002+31,509,019,1012 = 44,560,482,1492. Each root number in the series is 6 times the previous root number minus the earlier root number:  1, 52, 292, 1692, 9852

Or in other words:

(31,509,019,100, 31,509,019,101, 44,560,482,149) is the 14th Pythagorean triple (lengths of 3 sides of a right triangle), where 2 sides are consecutive integers.

31,650,544,836

[Math.]  Sum of the first 596 cube numbers:

13+…+5963 = 31,650,544,836 = (1+…+596)2 = 177,9062.

31,772,911,120

xy,zwv,abc,def

[Math.]  For any xy,zwv = 10,000 to 99,999, there are always six 6-digit numbers abc,edf such that xy,zwv +abc,def is equal to one of 6 digit-rotations of 142,857 and the number xy,zwv,abc,def is a multiple of 142,857.

For any xy,zwv  = 10,000 to 76,922, there are always twelve 6-digit numbers abc,edf such that xy,zwv +abc,def is equal to one of 12 digit-rotations of 076,923 or 153,846 and the number xy,zwv,abc,def is a multiple of 76,923.
