Presentation

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

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

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