........3.......18......60......150
1.......7.......25......65......140
........................6.......42
................12......84......324
........12......84......324.....924
........6.......42......162.....462
4.......32......132.....392.....952
........................10......80
................30......240.....1050
........10......90......420.....1400
........30......240.....1050....3360
1.......11......56......196.....546
........................15......135
................60......540.....2640
........15......165.....900.....3420
........................21......210
................35......385.....2205
........................28......308
........................1.......19
therefore this sequence begins
