Presentation

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

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

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