Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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