When is the next EB coming out?

[The_Mark]

I have signed a contract, where I get paid 150.000 euros a week and I get 10 free girls of my choice to have fun with till 2015 in exchange not to tell the secret when the new EB comes.

Trust me, I will surely won't.

Waitaminit, I'm not getting anything! I demand a contract of my own, 'lest I slip out something!

Just to show you I'm serious, I'll tell you that the next public release of EB will happen within d days, where

d = f(5; 4), where

f(m; n) = n + 1, when m = 0
        = f(m-1; 1) when m > 0 and n = 0
	= f(m - 1; f(m; n - 1)) when m > 0 and n > 0
