Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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