End of the first line, that sequence PE, PO, PF.

Should the O be a D ? Probably, obviously ? it should be.

Should they though be in the order PD, PE, PF, like at the start of the second line ?

If I have to worry about whether or not there are typos in the question, I really can't be bothered with it.
