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