Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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