Hi Dear Neil,

Does it also makes sense to merge A045620 and A084664

A045620  Digits of cube contain digits of square.
 1, 5, 10, 25, 50, 65, 100, 146, 250, 405, 500, 510, 521, 615, 650,
768, 945, 965, 1000, 1004, 1040, 1050, 1085, 1126, 1145, 1203, 1216,
1219, 1222, 1452, 1460, 1476, 1480, 1482, 1638, 1706, 1878, 2002,
2020, 2199, 2204, 2260, 2276, 2326, 2450, 2470, 2476 (list; graph;
listen)

 A084664  Digits of n^3 include digits of n^2.

 0, 1, 5, 10, 25, 50, 65, 100, 146, 250, 405, 500, 510, 521, 615, 650,
768, 945, 965, 1000, 1004, 1040, 1050, 1085, 1126, 1145, 1203, 1216,
1219, 1222, 1452, 1460, 1476, 1480, 1482, 1638, 1706, 1878, 2002,
2020, 2199, 2204, 2260, 2276, 2326, 2450, 2470, 2476 (list; graph;
listen)
