Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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