Presentation

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

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

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