 A060852 Sum of number of pips on dice in shape of Platonic solids. 3
 10, 21, 36, 78, 210 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS This is obviously a finite sequence, since there are only five Platonic solids. LINKS Wikipedia, Dice. EXAMPLE The third number in the sequence is 36 because the third Platonic solid has eight faces and the pips on an eight-faced die add up to 36 [by sum_1^n(n) = 1/2 * n * (n+1), so 1/2 * 8 * 9 = 36 for n = 8].
