Examples

## moa is the number of columns of an oa
moa <- rep(seq(4,40),3)
## t is the strength used in the construction
##      the oa must have at least this strength
t <- rep(2:4, each=37)
## numbers of columns for the combination
mbounds <- mapply(mbound_LiuLiu, moa, t)
## depending on the number of levels
## the number of runs can be excessive
## for larger values of moa with larger t!
## t=3 and t=4 have the same number of columns, except for moa=4*j+3
plot(moa, mbounds, pch=t, col=t)
