I am correcting A112629 (inserting 121) and get

9,25,49,121,169,289,625,841,961,1225,1681,1849,2401,3025,4489,5929,6889,10201,
11881,13225,14161,15625,17689,19321,20449,22801,24025,24649,25921,32041,32761,
39601,41209,44521,48841,49729,55225,57121,69169,76729,80089,82369,87025,90601,
94249,96721,104329,105625,108241,112225,113569,120409,124609,142129,143641,
148225,151321,165649,..

So far this is the same as A110284. Does this trend continue?
