I can't understand Primitive basis function |

- Dear Users OpenMX! Please help me to explain some paragraphs on openmx_manual:
"where ... 'H4.0-s2p1' of the basis function is introduced, ..., and 's2p1' means that two s-orbitals and one p-orbital in the file are used. In this case, totally eight basis functions (2x1+3x2=8) are assigned for 'H'."
I just wonder why is 8 functions for H? I think that this is 5 (1AO_1s, 1 AO_2s and 3 AO_2p), maybe I am not total right but I can't understand: 2x1+3x2=8 I'm very sorry for that question. Thank you in advance.
