Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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