Does anyone know where we can find a table mapping between the Sphinx3 phoneme codes and IPA symbols, or else give a set of examples mapping between written forms of English words and corresponding Sphinx phoneme codes so that such a table could be built?

There is no direct mapping between IPA and CMUDict
or else give a set of examples mapping between written forms of English words and corresponding Sphinx phoneme codes so that such a table could be built?
Did you try to look in the dictionary itself? :)
For some documentation check the dictionary page, it has some information about phoneset:

There's a couple of slightly strange things that happened on the way from ARPA to CMU, one of which was the disappearance of AX or 'ə', which is an insanely useful thing to have. You sort of have to consider which direction to drift a schwa on a case by case basis, the whole "always use AA" thing often causes serious trouble. AA or 'ɑ' is the open back unrounded vowel, and moving all the schwas to the back is just crude.
Some other weirdness. You don't have a schwa, but the only rhotic vowel is a rhotic schwa, ER 'ɚ'. There are no central vowels, and anyone who isn't from the US East Coast knows the difference between 'ʉ' and 'u'
And let's not start the 'ɐ' argument again.
