A sequence puzzle

[franktaw at netscape.net]

Apparently, I didn't give enough terms to really disambiguate the 
sequence.  Here are 20 more.

105,2310,53130,212520,1062600,13813800,124324200,7,203,6090,188790,302064

Here are the first 20 terms of a sequence: 
 
1,2,6,12,60,3,21,168,504,2520,27720,4,52,364,5460,21840,371280,1113840,21
 
162960,5 
 
The puzzle is to determine the rule of formation.
