combine each 3 lines in one with sed 1

[w5000]

hello,
I found how to combine every 2 lines into one with sed:

sed 'N;s/\n/\ /'

but how to modify this sed oneliner to get it working for 3 lines?

ok, I googled something like:

sed 'N; s/\n//; N; s/\n//'

And what about this ?
sed 'N;N;s!\n!!g'

Hope This Helps, PH.
