%N Numbers m such that m^3 is the sum of nth group in partition of sequence of natural numbers.
%C Partition of sequence of natural numbers: {1}, {2, 3, 4, 5, 6, 7}, {8}, {9,..., 280}, {281,..., 297}, {298,..., 377}, {378, ..., ?}
%C sum of groups: 1^3, 3^3, 2^3, 34^3, 17^3, 30^3, ?
%C If instead of m^3 we look for m^2 then we get A000244.
%Y Cf. A000027, A000244.
