Triangle, square, pentagonal, hexagonal, heptagonal, and octagonal numbers are all figurate (polygonal) numbers and are generated by the following formulae: ~~~ Triangle P3,n=n(n+1)/2 1, 3, 6, 10, 15, ... Square P4,n=n2 1, 4, 9, 16, 25, ... Pentagonal P5,n=n(3n?1)/2 1, 5, 12, 22, 35, ... Hexagonal P6,n=n(2n?1) 1, 6, 15, 28, 45, ... Heptagonal P7,n=n(5n?3)/2 1, 7, 18, 34, 55, ... Octagonal P8,n=n(3n?2) 1, 8, 21, 40, 65, ... ~~~ The ordered set of three 4-digit numbers: `8128, 2882, 8281`, has three interesting properties. - The set is cyclic, in that the last two digits of each number is the first two digits of the next number (including the last number with the first). - Each polygonal type: triangle (`P(3,127)=8128`), square (`P(4,91)=8281`), and pentagonal (`P(5,44)=2882`), is represented by a different number in the set. - This is the only set of 4-digit numbers with this property. Find the sum of the only ordered set of six cyclic 4-digit numbers for which each polygonal type: triangle, square, pentagonal, hexagonal, heptagonal, and octagonal, is represented by a different number in the set.
