Presentation

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

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

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