All these cardinals are greater than or equal to $\\aleph_1$, the smallest uncountable cardinal, and they are bounded above by $2^{\\aleph_0}$, the [[cardinality of the continuum|0WC28W9DNM]]. Four cardinals describe properties of the ideal of sets of measure zero; four more describe the corresponding properties of the ideal of [[meager sets (first category sets)|0FQPYAY9PJ]].\n",
