Presentation

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

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

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