Examples
a(2) = 2 (a term in A180301); a(3) = 3 (three), so a(4) = 12 (twelve). The triangle starts: 1: 1 2: 2 3: 3 12 20 21 22 200 4: 4 6 10 12 20 21 22 200 5: 5 6 10 12 20 21 22 200 6: 6 10 12 20 21 22 200 7: 7 10 12 20 21 22 200 8: 8 9 10 12 20 21 22 200 9: 9 10 12 20 21 22 200 10: 10 12 20 21 22 200 11: 11 12 20 21 22 200 12: 12 20 21 22 200 13: 13 20 21 22 200 14: 14 16 20 21 22 200 15: 15 16 20 21 22 200 16: 16 20 21 22 200 17: 17 20 21 22 200 18: 18 19 20 21 22 200 19: 19 20 21 22 200 20: 20 21 22 200
