| | | | | For any of you interested, here's how I came up with the slopes formula: Layer 1 and 2 have no 2x2 slopes, they start at layer 3. Layer 3 has 4, layer 4 has 8, 5 has 12, etc. (add 4 to each layer). This gives the series: sum(0,0,4,8,12, ... (...) (26 years ago, 29-Jan-99, to lugnet.general)
