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