const string mirrorChar = "AHIMOTUVWXY";
int main(){
    string str;
    cin >> str;
    bool flag = true;
    for(int i =  ; i < str.length(); ++ i){
        if(mirrorChar.find(str[i])==string::npos) {
            flag = false;break;
        }
    }
    if(flag && str == string(str.rbegin(),str.rend())) cout<<"YES"<<endl;
