[Math.]  A base system of multigrade equalities:

1+8+10+17 = 36 = 2+5+13+16

12+82+102+172 = 454 = 22+52+132+162

13+83+103+173 = 6,426 = 23+53+133+163.

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. (

[Math.]  454+545 = 999 = 434+565

4542 = 206,116 & 206+116 = 322

5452 = 297,025 & 297+025 = 322

and

4342 = 188,356 & 188+356 = 544.

5652 = 319,225 & 319+225 = 544
