13+23+…+1943 = 357,777,225 = (1+2+…+194)2 = 18,9152.

358,024,691

[Math.]  Multiples of 012345679 by 2, 11, 20, 29, 38, 47, 56, 65 and 74 will yield all 9 rotations of 024691358: 024691358, 135802469, 246913580, 358024691, 469135802, 580246913, 691358024, 802469135 and 913580246. All numbers are missing digit 7.

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.
