 A059094 Numbers whose sum of digits is a cube. 4
 1, 8, 10, 17, 26, 35, 44, 53, 62, 71, 80, 100, 107, 116, 125, 134, 143, 152, 161, 170, 206, 215, 224, 233, 242, 251, 260, 305, 314, 323, 332, 341, 350, 404, 413, 422, 431, 440, 503, 512, 521, 530, 602, 611, 620, 701, 710, 800, 999, 1000, 1007, 1016, 1025 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,2 COMMENTS The first occurrence of a new cube value in sequence 1, 8, 27, 64, ... occurs at a great distance from each previous value. Consecutive terms differ by 1 iff they are of the form 999..999 and 1000..000 provided the number of 9s is 3*(u^3): that is 999 (length 3) whose digit sum is 27=3^3; 99..99 (length 24) whose digitsum is 216=6^3; 99.999 (length 81) whose digitsum is 729=9^3. - Carmine Suriano Mar 31 2014 LINKS Carmine Suriano, Table of n, a(n) for n = 1..390 EXAMPLE 999 has digit sum 9 + 9 + 9 = 27 = 3^3, so 999 is a term. PROG (PARI) isok(nn) = ispower(sumdigits(n), 3); \\ Michel Marcus, Jun 06 2014 CROSSREFS Cf. A007953.
