you may take one from righ part of this table, but if you take one from middle part you have to REVERSE it, mirorred, on set.
you may not take one from left column.

what does the P and the N at the end of each number down the columns stand for.

P is P-N-P type. N is N-P-N type. THE structure of the transistors. your type seeking is PNP. the emitter's arrow looking inside, at circuits.
