Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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