Could someone please help me with the Latex code for the symbol below?:
The symbol you are searching for is: \nleq
\nleq
Found via: http://detexify.kirelabs.org/classify.html
\usepackage{amssymb}
Another way (the original way before amssymb) is \not\leq
amssymb
\not\leq
\nleqsymbol requires\usepackage{amssymb}– egreg Feb 27 '13 at 22:26
