构建一个 LISP 机器需要多少个原语? 十个,七个还是五个?

On this site they say there are 10 LISP primitives. The primitives are: atom, quote, eq, car, cdr, cons, cond, lambda, label, apply.

http://hyperpolyglot.wikidot.com/lisp#ten-primitives

Stevey reckons there are seven (or five):

Its part of the purity of the idea of LISP: you only need the seven (or is 
it five?) primitives to build the full machine.

http://steve-yegge.blogspot.com/2006/04/lisp-is-not-acceptable-lisp.html

What is the minimum number of primitives to build a LISP machine (ie something that can run an eval/value function on LISP code)? (And which ones are they?)

(I can understand you could live without atom, label and apply)
