I tried it on a enwik9 100 mb slice and was able to compress it to 20 mb + 900kb transformer so 21mb.

I know the top submission was able to get it to 13 mb.

Still trying some ideas to get better compression.

Thanks for the link!

Maybe everyone should compress the 1st 100MB worth of digits of pi, for an apples-to-apples comparison?

Edit: oh wait that's too easy. Need to generate /publish random digits so everyone can use it.
