Presentation

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

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

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