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