More solutions to Puzzle 102 by Chris Nash  Chris Nash has given (7/8/2000) a qualitative jump in this search discovering a way of seeking candidates to cubes expressible as sum of 3 squares: D must be 3 modulo 8; then he shows a methodic way of looking for D^39 as a sum of squares. As a consequence of his method he could find plenty of new solutions and a very interesting example of D: "In particular, 90659^3 is the sum of three prime squares in FIVE different ways!.
