9,770,352

[Math.]  A base system of multigrade equalities:

1+6+7+17+18+23 = 72 = 2+3+11+13+21+22

12+62+72+172+182+232 = 1,228 = 22+32+112+132+212+222

13+63+73+173+183+233 = 23,472 = 23+33+113+133+213+223

14+64+74+174+184+234 = 472,036 = 24+34+114+134+214+224

15+65+75+175+185+235 = 9,770,352= 25+35+115+135+215+225. (References [??])

Multigrade equalities still hold by adding any integer n to every base term in both sides.  Hence, the base equality always has number 1 appearing in one side.

9,773,505
