A class of two-dimensional translation planes admitting SL(2,5)


A class of translation planes of order q^2 admitting SL(2,5) is described, constructed from replaceable A_5-invariant nests of reguli in a regular spread of PG(3,q), where q is odd and q+1\equiv0 (mod 5). The translation planes of order 29^2 in this class are determined.
