How to count number of avx and avx2 instruction set

The number of Intel SSE4.2 is exactly 313 assembly instruction sets(sum the Intel manual numbers). I want the same number for AVX and AVX2 but couldn't find any trusted reference. I found a reference that tells there are 292 instructions in AVX (page 1, Table 1) and its wrong and SSE4.2 is containing SSSE3 that they didn't count it. So how can I count the AVX/AVX2 instructions? (I thought to write a program and copy the Intel intrinsics guide to a text file and process it. But I need an easier way

This resource also provide an answer to this question:

Intel AVX is a comprehensive ISA enhancement that adds n ew functionality in addition to the compact new encoding format.

• A large number (200+) of legacy Intel SSEx instruction s are upgraded by the enhanced instruction encoding to take advantage of feat ures like a distinct source operand and flexible memory alignment.

• A moderate number (< 100) of legacy 128-bit Intel SS Ex instruction have been promoted to process 256-bit vector data.

• A number of new data processing and arithmetic operatio ns (< 100), not present in legacy Intel SSEx, are added to Intel processors to be launched in 2010 and beyond.

There are 86 instructions in AVX and 137 instructions in AVX2 and totally 223 new instructions introduced by AVX and AVX2. I've copied the Intel intrinsics guide to a word format, deleted intrinsics functions, sorted the assembly instructions and deleted the duplicated instructions. This assumes that all instructions have corresponding intrinsics
