Presentation

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

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

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