        for (int[] relation : relations) {
            if (relation[0] != relation[1]) {
                boolean symmetric = false;
                for (int[] relationB : relations) {
                    if (relationB[0] == relation[1] && relationB[1] == relation[0]) {
                        symmetric = true;
                        break;
                    }
                }
                if (!symmetric) {
                    return false;
                }
