Presentation

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

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

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