Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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