Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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