EXAMPLE
First few rows of the triangle are:
1;
1, 1;
1, 1, 1;
1, 2, 2, 1;
1, 6, 12, 6, 1;
1, 12, 72, 72, 12, 1;
1, 20, 240, 720, 240, 20, 1;
1, 30, 600, 3600, 3600, 600, 30, 1;
...
Row 4 = (1, 6, 12, 6, 1) since ConvOffs transform of (1, 1, 2, 6) = (1, 6, 12, 6, 1); where A103505 = (1, 1, 2, 6, 12, 20, 30, 56, 72,...).
