[Math.] (1+2+…+16)4 = [(15+25+…+165)+(17+27+…+167)]/2.

 

343,286,784

[Math.]  Sum of the first 192 cube numbers:

13+23+…+1923 = 343,286,784 = (1+2+…+192)2 = 18,5282.

 

345,679,012

[Math.]  012345679 is the 9-digit period of the rational number 1/81 = 0.012345679012345679… or 0.012,345,679.

Multiples of 012345679 by 1, 10, 19, 28, 37, 46, 55, 64 and 73 yield all 9 digit-rotations of the number itself: 012,345,679, 123,456,790, 234,567,901, 345,679,012, 456,790,123, 567,901,234, 679,012,345, 790,123,456 and 901,234,567. All numbers are missing digit 8.

Multiples of 012345679 by a number from 1 to 80 of the form x (mod 9), where x = 1, 2, 4, 5, 7 or 8, will yield a 9-digit number, including all but one digit from 0 to 9. The missing digit is (9–x), again taking only values: 8, 7, 5, 4, 2 or 1. (Adding extra 0 to any 8-digit numbers). Its multiple by 81 is 999,999,999. 

 

xyz,abc,def

[Math.]  For any xyz = 100 to 999, there are always six 6-digit numbers abc,edf such that the sum (xyz+abc,def) is equal to one of 6 digit-rotations of 142,857 and the number  xyz,abc,def is a multiple of 142,857.

 

For any xyz = 100 to 999, there are always twelve 6-digit numbers abc,edf such that the sum (xyz+abc,def) is equal to one of 12 digit-rotations of 076,923 or 153,846 and the number xyz,abc,def is a multiple of 76,923.
