    FORMULA_ELEMENT_PATTERN: "(?:H[eogsf]?|L[iavru]|B[eahkri]?|C[arofmusenld]?|N[eiahopdb]?|O[sg]?|F[rlem]?|M[godtcn]|A[lrsgutmc]|S[icerngmb]?|P[uabotmrd]?|Kr?|T[icebmsalh]|V|Z[nr]|G[ade]|R[buhenagf]|Yb?|I[nr]?|Xe|E[urs]|D[ysb]|W|U)" = '(?:H[eogsf]?|L[iavru]|B[eahkri]?|C[arofmusenld]?|N[eiahopdb]?|O[sg]?|F[rlem]?|M[godtcn]|A[lrsgutmc]|S[icerngmb]?|P[uabotmrd]?|Kr?|T[icebmsalh]|V|Z[nr]|G[ade]|R[buhenagf]|Yb?|I[nr]?|Xe|E[urs]|D[ysb]|W|U)'

    Element-symbol alternation (all 118 symbols, folded into per-first-letter character classes). Gates formula matching so ordinary prose isn't read as a formula.
