Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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