Hello everyone :)

I have, say a list of list. Each element is a list of length 3 i.e.

myList={{x1,y1,z1},{x2,y2,z2},...{xN,yN,zN}}

Now, let's say I want to delete from this list the element which have
x=2 and 3 using DeleteCases.
This works :

DeleteCase[myList,{2,_,_}]
DeleteCases[myList,{3,_,_}]

but I would like to use

DeleteCases[myList,{{2,_,_},{3,_,_}}]

and this does not work...

How do I combine multiple patterns in DeleteCases ?

Thanks in advance.
