[seqfan] offset error in A155122 and others ?

[Simon Plouffe]

Hello,

  just a little glitch, there is an offset
error in sequence A155122,

also there are * errors in the formula :

it should read : 16+ 80*n + 140*n^2 + 100*n^3 + 24*n^4.

other lines are faulty as well.

I retyped the whole bunch :

Not sure about the offset.
