RFC1321 - MD5 algorithm document

Attempting to implement the MD5 algorithm.

I understand this:
Let [abcd k s i] denote the operation:
a = b + ((a + F(b,c,d) + X[k] + T[i]) <<< s)
...
Let [abcd k s i] denote the operation
a = b + ((a + G(b,c,d) + X[k] + T[i]) <<< s)

But I do not understand this:
Let [abcd k s t] denote the operation
a = b + ((a + H(b,c,d) + X[k] + T[i]) <<< s)
...
Let [abcd k s t] denote the operation
a = b + ((a + I(b,c,d) + X[k] + T[i]) <<< s)

Where the hell did "i" go and what is "t"??? Have I acquired an old RFC document?

MD5 MY ANUS

Ah, checked the Errata over at RFC. Turned out this had been corrected, but not updated in the RFC document in over 10 years.......

RFC should be replaced by a new standards authority! Let's call it 4chanDOCS! =)

Probably those t were meant to be i.

Poopdicknuts-san, you're as persistent in shitting up the board as ever. You should register yourself a formspring account, and when people ask you in earnest a question, you can promptly tell them to shove it up their ass and refer to them as a ``cocksucking dickless nigger faggot'' or however it is that you do when you address other people, all with unmatched order and efficiency.

Midge-what? Oh, that's right, your mommy must have walked in on you and given you a serious beating because you were grounded without Internet for having had an autistic hissy fit in French class. I hope your butt won't hurt too much after your spanking, penisface.

I understand this:
Let [abcd k s i] denote my dubz
