Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 4 generators on 28 points:

(1,2,4,3)(5,6)(7,10)(8,9)(11,12)(13,14)(15,19)(16,18)(17,20);(6,9)(7,11)(13,15)(14,17)(16,20)(18,19)(21,22,23,26,24,25,27,28);(1,2,4,3)(14,18)(17,19)(22,25)(26,28);(1,3,4,2)(5,7,8,11)(6,10,9,12)(15,20)(17,19)
