[seqfan] Re: polynomial-to-product transform

[zak seidov]

Thanks to Maximilian and Vladetta for Cf. A147557!!

My extended list differs with 

%V A147557 2,3,-1,9,-4,0,16,89,-52,60,-182,214,-620,966

only in sign of a(7)=+/-16 (A147557/me).

Anyone may wish to check this, plz 
(and submit b147557.txt),
thx, zak
