Equal sums and sums of six 5-th powers

 
 
A + B + C + D + E + F \; = \; G + H + I + J + K + L

A^5 + B^5 + C^5 + D^5 + E^5 + F^5 \; = \; G^5 + H^5 + I^5 + J^5 + K^5 + L^5
 

with   A = 1   and   B,   C,   D,   E,   F   <   200

I arranged the results to produce an arithmetic progression (A.P.) between the successive equal sums:

54, 72, 90, 108, 126, 144, 162, … are in A.P. with 18 as the common difference.
