What is the relation between these two:

1,2,3,6,7,9,12,15,18,19,21,24,25,27,30,33,36,37,39,42,43,45,48,51,54,55,57,60,63,66,69,72,73,75,78,79,81,84,87,90,93,96,97,99,102,105,108,109,111,114,115,117,120,123,126,127,129,132,133,135,138,141,
0,1,3,6,7,9,12,15,18,19,21,24,25,27,30,33,36,37,39,42,43,45,48,51,54,55,57,60,63,66,69,72,73,75,78,79,81,84,87,90,93,96,97,99,102,105,108,109,111,114,115,117,120,123,126,127,129,132,133,135,138,141,144,145,


or between these (pattern avoiding):

1,2,6,19,70,331,1863,11637,81110,635550,5495339,51590494,524043395,5743546943,67478821537,844983073638,11240221721390,
1,2,6,19,70,331,1863,11637,81110,

http://oeis.org/classic/?q=id:A177516|id:A177479
1,2,6,21,90,450,2619,17334,129114,1067661,9713682,96393726,1036348587,11998603710,148842430470,1969461102357,27688474234602,
1,2,6,21,90,450,2619,17334,129114,

(This probably demonstrates that Ron has even integrated idle CPU cycles
of his washing machine and toaster to crunch on some of the numbers...:-)
