    Hi, Seqfans


    I found a term of A055153 and A141645.


    http://www.research.att.com/~njas/sequences/A055153

    2^37*3^6*11*23*83*137*331*547*1093*(2^17+1)/3*(2^19+1)/3*(2^19-1)

    The first and second of the three large factors are Bateman, Selfridge,
Wagstaff prime  and the last one is Mersenne prime.

    I think that it is the last term of A055153.
