“…Let f (x) = (x 2 , x3 ) and the family of 3-parameter stable unfoldings F l (x, y, z, w) = (x 2 , x 3 + xy l + xz, y, z, w), l ≥ 1. Concatenating with a crosscap we obtain the bigerms{F l , g} : (x 2 , x 3 + xy l + xz, y, z, w) (x, y, z, w 2 , zw) .In this caseLif t(F l ) = (0, 0, 0, 0, 1), (0, 0, −1, lZ l−1 , 0), (0, Y, 0, X + Z l + W 1 , 0), (−2X, 0, 0, 3X + Z l + W 1 , 0), (0, X 2 + XZ l + XW 1 , 0, Y, 0), (2Y, 3X 2 + 4XW 1 + W 2 1 + 4XZ l + 2Z l W 1 + Z 2l ,0, 0, 0).…”
