• First numbers E = a(n) of two non-consecutive numbers (E, F) different from (C, D) = (A352222(n), A352223(n)), such that the sums of their cubes are equal to centered cube numbers and to at least one other sum of two cubes, i.e. A = B^3 + (B+1)^3 = C^3 + D^3 = E^3 + F^3.at n=8A352224
• a(n) = 3*(2*n - 1)*( 3*(2*n - 1)^3 + 1) / 2.at n=7A355752
