how many cell in a row that contain certain combination from a larger combination

Hi.
I came up with that solutions. I use helper columns to identify wether cell includes required set of numbers which all of them in one cell. then sum those 1"s to get total number

=IF(COUNT(FIND(ISNUMBER(MID($E$1,ROW(INDIRECT("1:"&LEN($E$1))),1)*1)*MID($E$1,ROW(INDIRECT("1:"&LEN($E$1))),1),A1,1))=COUNT(MID($E$1,ROW(INDIRECT("1:"&LEN($E$1))),1)*1),1,0)
