[Jprogramming] Puzzle

[Dan Bron]

   3 ([ p:^:_1&|: p:\) i.7
30 105 385 1001 2431

[Hint: the middle tine can be greatly simplified :]

PS: I'll gladly cede the title of Stupidest J Pun to anyone who can say it cleverly using &. . Not sure it'll improve your resume, but you can always break it out at cocktail parties.
