repeating matrices in a list

Suppose I have the following  square, non-negative matrices

g=matrix(c(0,2,4,0.25,0,0,0,0.6,0),3,3,byrow=T);

I want to create a list where this matrix is repeated multiple times. if I
do this brute force (manually), using

env <- list(g,g,g)

works fine. Yields

[[1]]
     [,1] [,2] [,3]
[1,] 0.00  2.0    4
[2,] 0.25  0.0    0
[3,] 0.00  0.6    0

[[2]]
     [,1] [,2] [,3]
[1,] 0.00  2.0    4
[2,] 0.25  0.0    0
[3,] 0.00  0.6    0

[[3]]
     [,1] [,2] [,3]
[1,] 0.00  2.0    4
[2,] 0.25  0.0    0
[3,] 0.00  0.6    0



But - for a variety of purposes, I need to 'automate' building said list. I
tried using rep

 env <- list(rep(g,each=3))

but this yields

[1] 0.00 0.00 0.00 0.25 0.25 0.25 0.00 0.00 0.00 2.00 2.00 2.00 0.00 0.00
0.00
[16] 0.60 0.60 0.60 4.00 4.00 4.00 0.00 0.00 0.00 0.00 0.00 0.00

Any suggestions/pointers to the obvious?

Thanks in advance...
