Presentation

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

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

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