Sorry, that was my bad.  I think I have fixed it up now.

Here are the required factorizations to demonstrate membership of 78 and 80,
but not 89, 95, 97, 98, 103, 104. (Others are ruled out because of n!+1
factorizations).

78!+2 = 2.577.1069.3389.6435049.1767365513.114886791444297161936182421452692846283.P52
80!+2 = 2.229.67384773611957979501943750969.P88
89!+2 = 2.1277.42901.5378159949931.18329483167904576214066484477.6810195626101031667062474517145920193.P51
